/*
 * How to setup clock using clock driver functions:
 *
 * 1. Call CLOCK_InitXXX() to configure corresponding SCG clock source.
 *    Note: The clock could not be set when it is being used as system clock.
 *    In default out of reset, the CPU is clocked from FIRC(IRC48M),
 *    so before setting FIRC, change to use another avaliable clock source.
 *
 * 2. Call CLOCK_SetXtal0Freq() to set XTAL0 frequency based on board settings.
 *
 * 3. Call CLOCK_SetXxxModeSysClkConfig() to set SCG mode for Xxx run mode.
 *    Wait until the system clock source is changed to target source.
 *
 * 4. If power mode change is needed, call SMC_SetPowerModeProtection() to allow
 *    corresponding power mode and SMC_SetPowerModeXxx() to change to Xxx mode.
 *    Supported run mode and clock restrictions could be found in Reference Manual.

 * Function Name : CLOCK_CONFIG_FircSafeConfig

 *                 In default out of reset, the CPU is clocked from FIRC(IRC48M).
 *                 Before setting FIRC, change to use SIRC as system clock,
 *                 then configure FIRC. After FIRC is set, change back to use FIRC
 *                 in case SIRC need to be configured.
 * Param fircConfig  : FIRC configuration.
